For example, the invention application with a publication number of CN102508522A and called as “touch screen protector” made public a containing plastic film and spacers distributed on the outer edge area of the plastic film. The shortcoming is that the patent provides particles on the rear side of the plastic film to produce an anti-static effect, which is a method with a complicated manufacture process. Besides, with printing particle mode adopted, the technical scheme of the invention application is easy to cause non-conformance products and non-durability (such as non-resistance to wearing) and it is unable to accurately achieve an equal interval between particles. Therefore, the particle distribution is not uniform that influences anti-static effect and such optical effects as avoidance of light splitting and increase of definition, etc.

  • Preferably, the heights of the convex parts are less than or equal to the thickness of the back adhesive layer.
  • Preferably, the convex parts form a dot array in any of the following shape distribution:
  • Fold line shape;
  • Grid shape;
  • Concentric ring shape; and
  • Multi-point radiating line shape.
  • Preferably, the convex parts are formed through pressing.
  • Preferably, there is an interval between the convex parts.
  • Preferably, the interval between the convex parts is 0.05-0.5 mm.
  • Preferably, the thickness of the back adhesive layer is 0.05-1 m.
  • Preferably, the thickness of the protection film is 0.1-1 mm and the thickness of the back adhesive layer is 0.05-1 mm.
  • Preferably, the printing layer is also included and the printing layer is placed between the protection film and back adhesive layer.
  • Preferably, the convex parts are in hemispherical shape, prism shape and cone shape.
  • In comparison with existing technologies, this invention has the following beneficial effects:
  • 1. After multiple convex parts on the back side of protection film are designed, static electricity can be eliminated (anti-static) and the application film is easy to apply.
  • 2. The convex parts are made by means of mould pressing with a simple and stable process, and the air pollution during particle spray coating is avoided with the requirement for air cleanness reduced.
  • 3. Through such design as providing convex parts on the back side, the application film becomes durable with a high product conformance rate.
  • 4. Through forming the convex parts by means of mould pressing, the interval between the convex parts can be accurately controlled so that the convex parts distribute evenly on the back side of protection film to realize a good anti-static effect and such optical effects as avoidance of light splitting and increase of definition. With particles being provided on protection film by means of spray coating, the requirement of even distribution can not be achieved due to difficulty in controlling the interval between particles.
